Hey no problem dude, hopefully he hasn't put waylander off, we need his powerful system and kernel knowledge for compiling, it does it really quick :eek:

found the source of the error tho:

Code: 
            // Old touchscreen sensors need to send a fake BTN_TOUCH (BTN_LEFT)

            if (rawEvent->scanCode == ABS_MT_TOUCH_MAJOR) {

                z_data = rawEvent->value;
                touched = (0 != z_data);
            }
            else if (rawEvent->scanCode == ABS_MT_POSITION_Y) {

                RawEvent event;
                memset(&event, 0, sizeof(event));
                event.when = rawEvent->when;
                event.deviceId = rawEvent->deviceId;

                event.value = z_data;

Are we using the generic touchscreen driver ?
Or ours ?

And? This is no error, it's just debug message for legacy touchscreens. I patched this lib to use that code

ok but what i'm thinking is it return this value in logcat upon first touch, not an error but should that be the right value?

D/InputReader( 173): Fake event sent, touch=0 !

I think the fake events were reversed

Oh yes , one more question .
Why does the ROM installation in CWM generate a random offset ?

right now we need to focus on the touch screen, i have noticed that 1 tap= holding down on left mouse button, while a second tap executes the task, equivalent to releasing the left mouse button after holding it down or a double tap

InputReader was changed after gingerbread, in ICS. And our touchscreens become to LEGACY. So, now we use legacy ts hack.

our touch is being registered as a long press, 1 touch produces this twice in my log

D/InputReader( 173): Fake event sent, touch=0 !
D/InputReader( 173): Fake event sent, touch=1 !
D/InputReader( 173): Fake event sent, touch=1 !

notice inputreader being called twice from just one touch
